Update: 2/27/2013

It’s time for the weekly update! The big news this week is that we finally got the prototype leg under closed-loop control – woohoo! We also continued work on the hydraulic power unit frame, made spacers for the powertrain, and started the final round of design on the chassis and leg based on lessons learned from the prototype leg. Check it all out in the video below:

In this coming week, we’ll be doing a lot of tuning of the control loops that govern the leg’s motion, continuing the final design process for the legs, and pushing ahead with the hydraulic power unit integration. Stay tuned – we’re starting to pick up some serious speed!

Gui Cavalcanti received a General Engineering degree with a Robotics concentration from the Olin College of Engineering. He worked as a robotics engineer and systems integrator at Boston Dynamics, working on cutting edge mechanical design and systems integration for highly dynamic legged robots like BigDog, AlphaDog, and PETMAN. He was the Systems Integrator for the LS3 project, coordinating the joint engineering and development of multiple subcontractors and engineers. Over the course of his career he has also developed the mechanical systems for a robotic tuna, several robotic snakes, an ornithopter, and several other robotic animals. In his spare time he builds ridiculous things with ridiculous people, like a flotilla of SUV-sized rubber duck boats to take on the water on the 4th of July.

  1. Hi guys,
    I’m following your awesome project for about 10 months now and I really love what you’re doing! Your progress so far is amazing and I hope to see your giant robot walking around soon.
    Just one question: Where’s your promised weekly update? It has been nearly 3 weeks since you uploaded the last video. So please post an update, I’d love to see stompy growing. 🙂

    1. Working on it now! We were trying to ‘save up’ an update for a big reveal, but it enough time has passed that we just need to post what we have so far. Sigh… that’ll teach us.
